Abstract

This Master Thesis deals with analysis of the protocols from annual and five years
inspections of the technical condition and suitability for use of the buildings in
Olsztyn, Poland. The study starts by exploring the main technical condition of
particular buildings elements. The main goal is to analyze statistical possibilities to
this data, and to fit models describing possible changes and damage of the buildings
elements in the future.
The obligation to control the technical condition of the buildings due to the provision
of Polish Act - Construction Law, from 7 VII 1994. Data used in the analysis were
collected during inspections of the technical codition and suitability for use of the
buildings, in Olsztyn. Information come from inspections which were carried out from
2012 to 2016, in exception of year 2014. In total, 301 and one protocol have been
collected, and they describe the condition of 81 buildings.
The collected data has been modified using scripts - written in Bash and Python 2.7,
to easily access table in .xls format. Analyses of the data were made in Minitab 17,
and they include: material distribution, individual and averaged condition profiles
evolution, conditional probabilities for material given condition and viceversa, as well
as plots and conditional probabilities for condition and urgency of intervention.
The aim of the analysis was to fit models describing changes of technical condition,
that occur during the use of buildings. In the Thesis statistical summaries of the 28
building elements has been described. Detailed analyses were made for four of them
- roof covering, facades, plinths and bands. The results obtained were used to fit
models in order to predict the progression of the technical status of the building
facades in the future.
Main conclusions from this Master Thesis come from, on one hand, deficiencies that
have been found during the data management and, on the other hand, discussions
and specific conclusions derived from the statistical forms in Appendix F, for
everyone of the elements in the protocols of inspections.
